Excellent mod and very useful, however there are a couple bugs that I've noticed. Sometimes in a populated area if you use the command to freeze the action and enter screenshot mod, some characters that go out of view will sometimes disappear from the world.
Another bug is that if you're being chased by the police and you enter screenshot mode, the passenger officer in the police vehicle behind you will suddenly appear outside of the vehicle and when you enter the game action again, the officer will suddenly exit the vehicle in real time.
